When it comes to modern metalworking, the ability to drill small hole in metal with accuracy, speed, and repeatability is more than a technical requirement—it’s a competitive edge. From aerospace components and automotive parts to medical instruments and consumer electronics, manufacturers are under pressure to produce micro holes that meet strict tolerances. Traditional drilling methods often fall short, leaving rough edges, inconsistent depths, or simply failing to achieve diameters below 1mm. This is exactly where DUOMI CNC machines step in.
At DUOMI CNC, we specialize in customized CNC drilling machines built to tackle the toughest demands of small hole and micro hole drilling. If you’ve been struggling with slow production, tool wear, or limited precision, keep reading—you’ll see how the right machine can transform your workflow.
Why Drilling Small Holes in Metal Is So Challenging
Traditional Pain Points
Drilling a small hole in stainless steel, aluminum, titanium, or copper may sound simple, but manufacturers know it’s anything but:
- Tool Breakage – Conventional drills often snap when attempting to bore 0.05–3mm holes in hard metals.
- Heat Buildup – Small diameters mean less space for chip evacuation, which causes overheating and poor finishes.
- Inconsistent Precision – Manual drilling or outdated machines rarely maintain ±0.01mm accuracy.
- High Labor Costs – Skilled operators are needed to babysit the process, slowing down productivity.
The Industry Demands More
Global industries are shifting toward miniaturization and lightweight design. That means the ability to drill micro holes in metal parts is no longer optional—it’s essential. Manufacturers need machines that can deliver speed, stability, and automation without sacrificing accuracy.
DUOMI CNC – The Smarter Way to Drill Small Holes in Metal
DUOMI CNC has engineered a new generation of machines specifically designed for high-precision small hole drilling. Unlike conventional drill presses or bench-top tapping machines, our CNC drilling solutions are:
- Customizable in size and travel – from 400mm up to 13 meters, tailored to your part dimensions.
- Ultra-precise – achieving micro hole diameters from 0.03mm to 30mm with repeat positioning accuracy of 0.01mm.
- High-speed – capable of up to 60,000 rpm spindle speeds for smooth, burr-free finishes.
- Easy-to-use – no programming experience required; workers can operate after simple training.
- Cost-saving – automation reduces reliance on skilled labor while boosting output.
When you partner with DUOMI CNC, you’re not just buying a machine—you’re investing in a long-term production advantage.
